T 0 all whom it may concern:

Be it known thatI, Monnis Hmsrrrrnnn, a citizen of the United States,residing at borough of Brooklyn, New York, in the county of Kings andState of New York, have invented certain new and useful Improvements inBlanks for Slippers, of which the following is a specification.

My invention relates to a blank for slippers of the type commonly termedboudoir slippers and usually made of felt. An object of the invention isto provide a blank whereby the uppers of such slippers can be cut outwith almost no waste of cloth.

Another object is to so form the blank that it will retain its shapewhen steamed and during the process of manufacture instead of falling inat the sides as is the case with the blank at present used. The presentform is so troublesome that some manufacturers have even been nailingthe blank to the last.

Other objects will be evident from the following detailed descriptionand the appended claims.

In the drawings:

Figure 1 is a plan view of a single blank.

Figure 2 is a plan view of a plurality of blanks as they are cut from apiece of cloth.

Figure 3 is a plan view of the tongue piece.

Figure a is a side elevation of the two pieces assembled, showing thefirst step in the manufacture of the slipper.

The blank A has the form shown in Figure 1, with curved sides 1 and astraight out base 2. from a point 4: the desired distance from the toeto the center 5 of the base or heel 2. The curve of the side is soselected that the portion from 6 to 7 is a reverse of that from 7 to 8.This is clearly shown in Figure 2 where it is seen that the point 6 onthe side of each blank correspondsto the point 8 of the adjacent blankwhich is turned in the opposite direction. Due to this fact the blankscan be cut out of a piece of cloth as shown in Figure 2 and the onlywaste will. be the small portions B.

This reverse arrangement of the curves is a very important feature of myinvention as it permits the saving of a large amount of material. Theseblanks were formerly made with the side from 7 to 8 approximatelystraight, and they could not be cut out as shown in Figure 2 without thewaste of an unnecessary amount of material.

It is out along the median line 8- It was also the previous practice tomake the cut 3 straight from the point 5 for approximately two-thirds ofthe distance to the point 4, and to out out an oval shaped pieceextending from this point to the point 4-, which oval shaped piece ofmaterial was wasted. An advantage of my blank is that this waste also isavoided.

The blank A constitutes the whole upper of the usual felt slipper withthe exception of the part 9 shown in Figure 3 which is of the form shownand is sewn in between the parts of the blank A as shown in Figure 4E.The apex 10 of the part 9 registers with the point 4 or end of the cut3, and its sides as far as the point 11 are sewn to the sides of thematerial separated by the cut 3. This is clearly shown in Figure 4. Thetwo parts of the base or heel 2 are fastened by a seam as indicated at12 in Figure 3.

Moreover it is to be noted that the side of the slipper blank is acontinuous curve, and this curve from the point 1 to the heel portionserves a useful purpose in that it provides an allowance of materialwhich obviates the necessity of pulling it up or tacking it to the lastafter steaming. Notwithstanding the saving of material, that which isused is so formed that the manufacture is greatly facilitated.

This blank can be more readily and efficiently cut by means of dies thancould the old form because of the straight median cut. The part 9 may beof varying shapes and sizes according to the choice of the maker, andthe curve of the side of the blank A may be varied. It is only essentialthat approximately one half of the curve shall be a reverse of the othehalf and that the blank shall have the straight median cut illustrated.It is to be understood however, that the invention is to be regarded aslimited only by the scope of the appended claims.

I claim as my invention:

1. A blank for the uppers of slippers comprising a single piece ofmaterial with a straight out heel or base, and curved sides, the curveof approximately one half of each side being a reverse of the curve ofthe other half, so that the sides of two blanks lying adjacent eachother and pointing in opposite directions will coincide throughoutalmost their entire length.

2. A blank for the uppers of slippers comprising a single piece ofmaterial with a straight out heel or base, a median cut from the centerof the heel to a point relatively sides, the curve of approximately onehalf near the toe, and curved sides, the curve of of each side being areverse of the curve of 10 approximately o11e-half of each side being athe other half; and a tongue piece fastened reverse of the curve of theother half. with its apex at the toe end of said median 3. A slipperupper formed from a single out. piece of material having a straight outheel, In testimony whereof I have aflixed my a median cut from thecenter of the heel to signature. a point relatively near the toe, andcurved MORRIS HIRSHFIELD.
